X A constantly sufficient differentiation can not be guaranteed.
For this reason the influencing parameters always have to be analyzed and matched together with
the customer in advance.
5.5 New SIPLACE Vision Functions for 702 Station SW
A range of new functions have been introduced with SIPLACE Vision SW 4.0.1 4 for station SW 702.
These functions were not available in 605.01 or 701.0x.
Require separate group description:
this function can now be enabled from the SIPLACE Vision teach interface. Programming which uses
special SIPLACE Vision parameters will automatically enable this separation of the group
description.
Changed face down recognition:
The face down recognition has been extended to support more component shape types. It now also
includes a lead length inspection.
Lead recognition for Gullwing and Wraparound:
These lead types are now checked for the lead width.
You can also check the linearity of the lead measuring edges within a certain group.
Rectangle:
There is now a new rectangular feature for optical recognition of Nonstandard.
Fiducial recognition:
The tolerance of the bar width in cross or double cross fiducials has been increased from 20% to
30%. Other fiducial tolerances remain at a maximum of 20 % for accuracy purposes.
The flux inspection described for 605 and 701 remains in the 702 SW.
For a detailed description see above.
ATTENTION:
The procedure does not return a value for the layer thickness of the flux on the coated ball.

5.5.1 Face Down Recognition
The face down recognition of components has been extended from (only) CHIP to now also support
BareDie, molded, SOxx, QFP, SOT, DPACK, Socket, Connector, Nonstandard, (on component shapes
with wraparound and gullwing leads). It is not used for ECV and MELF!
The measurement function can be enabled separately in the geometry program section "
Special
Measurement Options
".
The size of the face down recognition field (FaceDown Region Of Interest) can now be individually
specified.
This face down recognition has been extended to include a lead length measurement for CHIP and
molded component shapes. This enables you to differentiate between component images with the same
dimensions or to use another face down recognition run.
The measurement function for checking the length can be separately enabled in the geometry program
section "
Special Measurement Options
".
The components on the left in each of the following diagrams need to be placed.
5.5.2 Lead Measurement
Lead width inspection
The lead width inspection has now been extended from a size determination for lead recognition filters
to an active width measurement function.
This measuring function is switched on in the geometry program area
"Special Measurement Options".
Application: If a SO2 (SOD323) is taken up sideways on the nozzle, this was previously only recognized
if the lead filters failed.
NOTE:
Please note that these surface structures are NOT usually specified in the manufacturer's data.
This means that the manufacturer could alter this feature in any production batch.
With the new function (SV 4.0.1), the pin width is
measured actively during the inspection and must
match the programmed nominal width +/- width
tolerance factor (as shown, for example, in the
diagram on the left).

Colinearity
In the case of colinearity (see camera image), the
straightness of a group with the same features is
searched for.
Do NOT mistake this type of inspection with the
coplanarity check, in which the gullwing lead
height deviations (for IVP 3D sensor also the ball
height deviation) to a calculated lead level are
determined.
This measurement function can be separately
enabled in the geometry program section
Special
Measurement
Options.
This checks the lead beginning of wraparounds on
component shapes and the lead end of gullwings
in inspection mode.
When using lead groups with three or more leads,
we check whether the lead measurement edges
are on a calculated straight line with +/- colinearity
length tolerance. This tolerance value can be
individually set for each group and is therefore
independent of the lead length tolerance value.
The lead feature position is compared to the
calculated component angle for two pins in a
group. This function is active for the following CS
types:
SOxx, QFP, SOT, DPACK, Socket,
Connector, Nonstandard
